TST Accessory Compatibility Matrix: What Fits Which Model

TST lists most accessories against a named model, so the reliable path is model, then accessory category, then the exact listing, with the product page confirming the fit. Only a few parts are named for more than one model. Where a listing doesn't say, this page marks the cell "not verified" instead of guessing.

The Fit Matrix by Model

Each cell shows the listing as TST publishes it. "Not verified" means no listing or statement was found, which is different from "does not fit."

Three notes apply to the table:

1. The 20" Fender Set page describes all-metal fenders, front and rear, with mounting hardware. It doesn't name a bike. TST's Carrier and Buddy Pro pages both list it in their bundles, which is good evidence but not an explicit fit statement.

2. The 27.5" Fender Set page says the fenders are "designed exclusively for Flyer Step-over electric bikes." The Surfer's page lists a 27.5" fender set in its bundle, but the fender listing itself names Flyer, so confirm the Surfer fit with support.

3. The Buddy Pro bike page lists a 48V 15Ah battery, but the accessory listing is named for the "Buddy 20'' Folding Ebike" and doesn't say "Pro." Treat it as unverified for the Pro until support confirms the exact SKU.

The GT63 isn't mapped here because no accessory listing for it was verified.

The Shared Charger Needs a Check

The charger is titled "TST® Battery Charger for R9, R7 & Buddy Pro" at $69.99, which makes it the clearest shared item in the catalogue. The page description, however, says it charges "the R002's removable lithium battery," and one reviewer wrote that the website didn't make clear which charger the R9 used.

For an R9, R7 or Buddy Pro, the title controls. For an R002, the listing sends mixed signals. For a Carrier or Surfer, the charger isn't named at all. Matching voltage or amperage on two pages isn't confirmation, so send support your battery label before ordering. TST's charger compatibility article explains why voltage and connector shape alone aren't enough.

Parts Named for More Than One Model

Parts whose listing titles name several models are the real exceptions to fit by model.

TST also has a universal accessories collection holding a handlebar bag and a bag, phone holder and lock set. The collection name isn't a fit statement for any particular bike, so read each listing before ordering.

What should I check first? Work through these steps:

1. Open your model's collection: R002, R7, Carrier or Buddy. The full accessories collection covers every model.

2. Look for your model's exact name in the listing title or description. A listing that names a related model is a question for support.

3. Treat size or family names such as "20"" or "27.5"" as part of the SKU, not as a shortcut for "fits my bike."

4. For a battery or charger, send support your model, purchase date and photos of both labels.

Questions and Checks Before Ordering

Can I use an R7 fender set on an R9?

Not verified. The R002, R7 and R9 each have their own fender set listing, and no page says they are interchangeable. Order the set named for your bike.

Can I put an R9 battery in an R7?

Not verified. The R9 battery listing says it is compatible with the R9 dual-battery bike, and the R7 has its own battery listing. Don't try the swap unless TST support confirms the pairing in writing.

Is the 20" fender set for the Carrier or the Buddy Pro?

TST bundles it with both bikes, but the fender page names neither. Ask support to confirm for your exact bike.

Which rack fits the Carrier versus the Buddy Pro?

The Carrier Rear Rack is described as custom-built for the Carrier 20''. The Buddy Pro's rack ships in the box, and a separate listing for it wasn't verified. TST's rear rack compatibility guide covers what to check before buying one.
